BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a paddle racket.

Description of the Prior Art

In order to maintain posture and physical health, various sports havebecome an indispensable part of people's daily life. When performingvarious sports, it is necessary to use or be equipped with differentcorresponding sports equipment.

For example, a variety of ball sports use rackets to play. Examples ofsuch rackets include tennis racket, squash racket, badminton racket, andcricket racket, etc. A racket includes a striking portion and a handle.The striking portion includes a frame body and a striking member (suchas a plate, net wire or the like) disposed with the frame body. If thestriking member is of considerable thickness and solid structure, itrequires a large amount of raw materials (plastic, wood, metal, etc.)for producing the racket, which increases the production cost and causesa heavy weight of the racket unfavorable for play.

The present invention is, therefore, arisen to obviate or at leastmitigate the above-mentioned disadvantages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 to 5 for a first preferable embodiment of thepresent invention. A paddle racket 1 of the present invention includes aframe body 10, a three-dimensional web core 20 and two striking surfaceportions 30.

The frame body 10 includes a frame wall 11 and a handle 12 connectedwith the frame wall 11, and the frame wall 11 defines a receiving space13; the three-dimensional web core 20 is disposed in the receiving space13 and circumferentially connected to the frame wall 11, and thethree-dimensional web core 20 includes a plurality of channels 21 (mayextend linearly, or may be defined by frames of the three-dimensionalweb core 20 and extend non-linearly) disposed through thethree-dimensional web core 20 in a thickness direction of thethree-dimensional web core 20; the two striking surface portions 30 isdisposed on two opposing sides of the three-dimensional web core 20 andconnected to the frame wall 11, each of the two striking surfaceportions 30 includes a plurality of through holes 31, the plurality ofthrough holes 31 correspond to and are in communication with theplurality of channels 21. Whereby, the three-dimensional web core 20 hassufficient structural strength and light weight so that the paddleracket 1 can be operated swiftly.

Preferably, an inner side surface of the frame wall 11 is radiallyconcave, and an outer circumferential surface of the three-dimensionalweb core 20 is radially convex and connected with the inner side surfaceof the frame wall 11 which is radially concave, so that thethree-dimensional web core 20 can be firmly connected to the frame wall11. In other embodiments, the inner side surface of the frame wall 11and the outer circumferential surface of the three-dimensional web core20 may be flat surfaces. Preferably, the outer circumferential surfaceof the three-dimensional web core 20 is continuously annular andenclosed, which increases connection area and combination with the framewall 11.

In this embodiment, the frame body 10 is a reinforced fiber member, thethree-dimensional web core 20 further includes two side layers 22 whichare opposite to each other and a framework 23 which is integrallyconnected with and between the two side layers 22. The two strikingsurface portions 30 are reinforced fiber members and coated on the twoside layers 22, respectively. Reinforced fiber, such as glass fiber,carbon fiber or the like, is of properties of light weight and strongstructure. With the two side layers 22, the two striking surfaceportions 30 can be made to be more flat. The two side layers 22 may bemade from fiber cloths pre-impregnated and coated on the two strikingsurface portions 30 after curing. Each of the two side layers 22includes a plurality of openings 221, the framework 23 includes aplurality of communication holes 231, and the plurality of communicationholes 231 correspond to and are in communication with the plurality ofopenings 221 of each of the two side layers 22, so that the resistancedue to air during operation of the paddle racket is reduced. In otherembodiments, the three-dimensional web core 20 and the two strikingsurface portions 30 may be made from the same material and integrallyformed of one piece, and thus it is easy to manufacture.

Preferably, the three-dimensional web core 20 is made from lighthardening resin (UV light hardening resin), which provides good supportand sufficient elastic deformability. Light hardening resin is hardenedby light projecting on predetermined regions, which is easy and quick tomanufacture. For example, the light-hardening resin is contained in acontainer with a transparent bottom side; a platform is immersed intothe light hardening resin in the container and close to the bottom sideof the container; according to patterns of various cross-sections of thethree-dimensional web core 20 the light is projected onto and hardensparts of the light hardening resin on the platform to form a part of thethree-dimensional web core 20. The platform is moved away from thebottom side of the container step by step, and finally thethree-dimensional web core 20 is grown. The manufacturing process issimple, fast and of lower manufacturing cost. The three-dimensional webcore 20 may be formed by using any of other forms of 3D printingtechnology.

Preferably, the three-dimensional web core 20 further includes a firstportion 24 and a second portion 25 which is farther from the handle thanthe first portion the handle 12, and the second portion 25 has a densityper unit volume greater than a density per unit volume of the firstportion 24. Whereby, it has better structural strength and swing inertianear the sweet center (near the second portion 25) of the paddle racket1, which improves the swing effect and increases durability.

In other embodiments, the frame wall 11 further includes a partitionportion 111, the partition portion 111 extends radially form an innerside surface of the frame wall 11, and the partition portion 111 ispreferably a reinforced fiber member. The three-dimensional web core 20a is disposed on two opposing sides of the partition portion 111, andthe three-dimensional web core 20 a is connected to the frame wall 11and the partition portion 111 by the adhesive material 40. The partitionportion 111 may extend continuously and diametrically across thereceiving space of the frame body, the partition portion 111 includes aplurality of penetration holes (112) 112, the plurality of penetrationholes 112 correspond to and are in communication with the plurality ofchannels 21, the three-dimensional web core 20 a includes a first framebody 26 and a second frame body 27 disposed at opposing sides of thepartition portion 111, the first frame body 26 and the second frame body27 are connected to the frame wall 11 and the partition portion 111 bythe adhesive material 40 (as a second embodiment shown in FIGS. 6 and 7); the partition portion 111 a may include an annular flange andannularly connected with the inner side surface of the frame wall 11,the three-dimensional web core 20 includes a first frame body 26 and asecond frame body 27 disposed at opposing sides of the partition portion111 a, the first frame body 26 and the second frame body 27 areconnected to the frame wall 11 and the partition portion 111 a by theadhesive material 40, the first frame body 26 and the second frame body27 are connected by the adhesive material 40 (as a third embodimentshown in FIGS. 8 and 9 ), and the first frame body 26 and the secondframe body 27, preferably, each include an annular recess 261, 271 atthe peripheral portion, the partition portion 111 a is received withinthe annular recesses 261, 271 of the first frame body 26 and the secondframe body 27, for providing flat striking surface portion and strongcombination. The partition portion can increase the structural strengthand paddling effect, and the first frame body and the second frame bodycan be separately made and assembled so that the manufacturing isconvenient and fast.
